Please update to a newer xf86-video-ati snapshot. You are missing some patches required for proper support with kwin. Please reopen if you are still having issues with a newer snapshot. Unfortunately, still same issue with 7.0.99+git20121126.60cd6cea snapshot. Tested in Serious Sam 3. Still reproducible with radeon 7.0.0 and newer git snapshots. Still reproducible with radeon 7.1.0. Tested on native Left 4 Dead 2. 7.10 is old please try with at least 9.1 Isn't 7.1.0 is latest version of the driver? http://www.x.org/wiki/radeon If you talking about Mesa - sure, I already tried Mesa 9.1.1 and 9.2-git. Still issue with Linux 3.11rc5, radeon driver 7.1.99+git20130730.6a278369, Mesa 9.2.0~git20130729 and KDE 4.11rc2. Not reproducible anymore. |

Created attachment 69414 [details] Example of artifact Hello! Please look at attached screenshot - there is triangle where we still see part of old frame, that was displayed on screen few frames before. I doesn't sure about terminology, but from my point of view looks like rendering in this triangle is lag behind rest of the screen. This issue happen for me only for applications launched with enabled offloading rendering (DRI_PRIME=1). It's reproducible not only in "Left 4 Dead 2" but also in other applications. Even in Chromium (if you launch it with "--ignore-gpu-blacklist" option that enabled hardware rendering on Mesa, and "DRI_PRIME=1" that enable offloading rendering) display same artifact (triangle) while scrolling pages. Also you may notice this artifact in glxgears, if you you run it in fullscreen mode. Software: Kubuntu 12.10 x86_64 updated from Xorg Edgers PPA. Mesa: 9.1~git20121029.00e6819e libdrm-radeon1: git20121025.bc494b31 xserver-xorg-video-radeon: git20120928.e8cb0b72 xserver-xorg-core: 1.13.0+git20120920.70e57668 Enabled or disabled V-Sync in KWin settings doesn't make the difference. Enabled or disabled V-Sync in game settings doesn't make the difference. Screenshot taken with stock Kubuntu kernel (3.5.0-17). With 3.7rc3 kernel issue still reproducible, but just a bit less noticeable.
